Lylat Cruise is pretty annoying when I'm using Peach. The tilting stops me from low floating most of the time, and it also makes recovering with Peach's Up + B somewhat difficult. Since Peach's more reliable kill moves are her aerials, this makes it even more difficult to KO people with Peach than it normally is (and it's already extremely difficult).

Pirate Ship, for some reason, I'm just terrible on. Maybe it has to do with the stage hazards distracting me from the battle...

Spear Pillar. The gravitational pulls, and every other annoying Stage shifts, are effing aggr(o,e?)vating. Plus, this Custom Stage skittles made that is basically a bunch of blocks (falling!) that are miscilanily placed everywhere.
